Description

Reinforcement soil structure, its reinforcing material, connecting material and construction method {REINFORCEMENT SOIL STRUCTURE, REINFORCING MATERIALS THEREFOR, CONNECTING MATERIALS AND WORKING PROCESS METHOD}

The present invention as a wall material, for example, while installing a plurality of wall panels adjacent to each other in the vertical direction and the horizontal direction, reinforcement earth structure is built by filling the fill material for each layer thickness on the back side and laying the reinforcement material for each layer thickness after voltage, It relates to the reinforcement used in this reinforcement soil structure, the connection between the wall material and the reinforcement, and the construction method of the reinforcement soil structure.

For example, Figure 15 (a) shows an example of a conventional reinforcement soil structure, and fills the fill material (30), which is mainly based on the fineness of the particles, such as earth and sand, crushed stone in a predetermined layer thickness, After the voltage is applied, a reinforcing material 31 made of reinforcing bars, strip steel, or the like is disposed between the layers.

In addition, the wall panel 32 is provided adjacent to each other in the vertical direction and the horizontal direction so as to form a plurality of continuous vertical wall surface (normal surface) or inclined wall surface as a wall surface material at the tip of the fill material 30, each wall panel 32 is The front end of the reinforcing material 31 is connected to the receiving bracket 33 protruding from the rear portion thereof, thereby being fixed to the front end of the fill material 30.

Moreover, stacking adjustment of each wall panel 32 is performed so that the wall panel 32 may not incline at the time of construction.

Up to now, the stacking adjustment of the wall panel 32 is performed by reinforcing material 31 placed in the fill material 30 and the wall panel 32 provided at the tip of the fill material 30 as shown in FIG. 15 (b). The turnbuckle 33 was connected, and the turnbuckle 33 was appropriately rotated to change the tension of the reinforcing material 31 properly.

However, the turnbuckle 33 has a complicated structure because the screws for screwing the reinforcement 31 side and the wall panel 32 side to the opposite threads are formed on both ends of the axial direction, so that the construction is complicated. In general, there was a problem that the cost is high and the construction cost is high.

In addition, if the part where displacement is most easily caused by the relative displacement of the reinforcement 31 and the wall panel 32 accompanying the settlement of the fill material 30 has such a complicated structure, this part is easily destroyed by stress concentration. There was this.

In other words, if there are two connecting portions between the reinforcing material 31 and the wall panel 32, the construction is not only complicated, but a decrease in tensile strength is inevitable, and there is also a problem in strength because a large bending load is also received.

The present invention has been made to solve the above problems, and in particular, the structure of the reinforcement soil which can simplify the stacking adjustment of the wall material with a simple structure and is extremely stable in terms of economics and strength, the reinforcement material used in the reinforcement soil structure, the connection between the wall material and the reinforcement material And to provide a construction method of reinforcement soil structure to be the subject.

In claim 6 to 5, the reinforcing soil structure of claim 5, as a reinforcing material, a rod-like material, a strip-like material, a steel material having an anchor body, a gold mesh, reinforcing grit or a di-textile is laid in the fill material.

The reinforcing material of the reinforcement soil structure according to the present invention is a reinforcement material which is filled in the fill material of reinforcement soil structure which is constructed by filling the fill material for every layer thickness and installing a wall surface material on the tip side of the reinforcement soil structure according to claim 7, It is formed with a connection nut screwed to the male screw portion and a connection plate or connection ring which is fixed to the connection nut and connected to the wall material.

In the reinforcing member of claim 8 to claim 7, the reinforcing member is formed of a rod-like body, a strip-like material, steel, reinforcing steel grit or diotextile.

The reinforcing member of claim 9, wherein the rod has an anchor at the end of the rod-shaped body, and the anchor body has a plate shape in which the cross-section with the central portion inflated toward the wall surface side and the circumference of which is folded to the wall surface side. It is formed.

The reinforcing member of Claim 10 to Claim 8 is formed by arranging a plurality of rods or strips in parallel, and attaching an arched anchor body on the opposite side of the wall surface between the rods or strips.

The construction method of the reinforcement soil structure of claim 11 according to the present invention, when constructing the reinforcement soil structure of claim 5 or claim 6, install the wall surface material, fill the fill material on the back side, laying the reinforcement material on it, and then connecting plate Or, the wall of the wall and the reinforcement is connected after adjusting the inclination of the wall by winding the connection ring.

1 to 13 show an example of the present invention, in which the earthen material 1, which is mainly based on the fineness of the particles such as soil and crushed stone, is filled at a constant layer thickness and reinforced after being energized. (2) is provided between each floor.

In addition, a plurality of wall panels 3 are arranged adjacent to each other in the vertical direction and the horizontal direction as wall materials at the front end of the fill material 1, and each reinforcement member 2 is provided in the receiving bracket 4 protruding from the rear part of each wall panel 3. ) Are connected to each other via the connecting bracket (5).

In addition, the anchoring body 6 is attached to the end part of the opposite side of each reinforcing material 2, respectively, and the reinforcing soil structure is constructed facing a road, a residential land composition, and the like.

The wall panel 3 is formed in a thin plate shape, for example, as shown in Figs. 2 (a) to 2 (e), and the wide ribs 3a and 3a which protrude in the same plane at the edges on both the right and left sides thereof are formed. Each is rushing. In addition, the back portion has a plurality of reinforcing ribs 3b and 3b having a substantially rectangular cross section or a rectangular cross section (two reinforcing ribs 3b having a roughly cross-sectional shape in the drawing) are successively arranged in parallel in the vertical direction. . The reinforcing rib 3b is not necessarily required and may be omitted.

The wide ribs 3a are projected from the center of the wall panel 3 to the bottom of the wall panel 3 in the shape of a rough ladder. Particularly, the corner portion is formed in an obtuse shape or an arc shape (ar shape), so that the fill material (1) Even if there is an unevenness in the earth pressure applied to each of the wall panels 3 at the voltage of, and the wall panel 3 is displaced due to floating settlement, etc., the edges of the wide ribs 3a are not easily subjected to stress concentration. It is not destroyed.

In addition, connecting portions 3c and 3d are formed at the periphery of the wall panel 3, respectively. The connection part 3c is formed continuously in the circumferential direction in the lower edge part and one side edge end, and the connection part 3d is respectively formed in the upper edge part and the other side edge end.

The joints 3c and 3d are coupled to each other between the wall panels 3 and 3 adjacent to each other in the vertical direction and the horizontal direction, so that the positioning of the wall panel 3 becomes easy, and at the time of voltage In spite of being a thin wall panel, since part of (1) can be reliably prevented from flowing out between adjacent wall panels (3) (3) or the wall panel (3) is displaced or displaced outwardly due to earth pressure. It is possible to build an extremely stable wall.

As another example of the wall panel, it may be formed in a substantially hexagonal plate shape as shown in Figs. 3 (a) to 3 (e), for example. In this case, the projecting portion 8 has a lower half horizontal edge 7c of the lower half and an oblique edge of both sides at the upper horizontal edge 7a of the upper half of the wall panel 7 and the oblique edge 7b of both sides thereof. The recesses 9 at the stage 7d are continuously formed in the circumferential direction of the wall panel 7, respectively.

In addition, the connecting holes 10 are formed in the horizontal rim ends 7a and 7c of the upper and lower ends, or the horizontal rim ends 7a and 7c of the upper and lower ends, respectively, at a constant depth.

Then, the projections 8 and the concave portions 9 are coupled to each other between the wall panels 7 and 7 adjacent to each other in the vertical direction and the oblique vertical direction, and the connection key 11 between the connection holes 10 and 10. The wall panels 7 are joined to each other by being inserted into each other.

In addition, a buffer member (not shown) made of synthetic rubber or the like is interposed between the convex portion 8 and the concave portion 9 to reduce stress concentration accompanying initial settlement of the fill material 1.

In this way, the wall panel 7 is formed into a hexagonal plate shape, and since the corner portion is an obtuse angle, the earth pressure is averaged without being well stressed. Therefore, the corner portion a does not break and the connection surface is increased so that it is not easily shifted. Further, the wall panel may be formed into a rectangular shape, an inverted T shape, or a cross shape as before.

As the material of the wall panel, fiber reinforced concrete in which reinforcing fibers such as glass fiber, carbon fiber or steel fiber are mixed in addition to the concrete panel may be used. Because wall panels reinforced with these reinforcing fibers can be reduced in weight due to their high strength, they can be constructed without using heavy machinery, especially in mountain construction.

The receiving bracket 4 is protruded several times at predetermined intervals in the up-down direction at the back portion of the reinforcing rib 3b. As the receiving bracket 4, for example, as shown in Figs. 4 (a) to 4 (d), two L-shaped brackets each having an L-shape and each having a vertically-connected hole 4b on one flange 4a are provided. The L-shaped brackets are arranged to face each other at regular intervals between one of the flanges 4a and 4a, and at the same time, the other flange 4c is attached to the rear of the reinforcing rib 3b. 12) or embedded in the concrete of the reinforcing rib 3b, or for example, omission of the flange 4c as shown in FIG. 13) is bulging by welding.

As another example of the receiving bracket 4, for example, as shown in Fig. 7 (a) (b), the connecting holes 4b having a vertical length are formed in two flange portions 4a which are substantially U-shaped and face each other in parallel. The receiving bracket 4 embeds the U-shaped portion 4d in the concrete of the reinforcing rib 3b, and the two flange portions 4a protrude in parallel to the rear side of the wall panel 3 to be attached thereto. It is becoming.

In addition, the receiving bracket 4 may be horizontally protruded, for example, as shown in Figs. 3A to 3E, and is shown in Fig. 3E without arranging two flanges 4a to face each other. You may form with one piece of flange as shown. In this case, the connection hole 4b may be a circular hole. Moreover, the edge part of the receiving bracket 4 may be embedded in the concrete of the wall panel 3 over the considerable length.

The connecting bracket 5 has, for example, a connecting plate 5a or a connecting ring 5b as shown in Figs. 4 and 8, and having the connecting plate 5a is provided at one end of the connecting plate 5a. The connection hole 5c is formed and the connection nut 5d is attached to the other end side.

A long nut or the like is used for the connecting nut 5d, and the connecting nut 5d is welded into the cutout 5e formed on the other end side of the connecting plate 5a or as shown in Fig. 4 (d), for example. It is attached simply by welding to the side part of the other end side of the connecting plate 5a. However, the former is preferable because the reaxial axis between the connecting plate 5a and the connecting nut 5d can be matched to avoid eccentricity.

The connecting bracket 5 thus formed is attached to the end of the reinforcing material 2 by screwing the connecting nut 5d to the male screw portion 2a formed at the end of the reinforcing material 2, and at one end of the connecting plate 5a. Is inserted between the flange portions 4a and 4b of the receiving bracket 4 and is also connected between the connecting hole 5c of the connecting plate 5a and the connecting hole 4b of the receiving bracket 4. It is connected to the wall panel 3 by tightening.

At that time, the connecting nut 5d is appropriately wound together with the connecting plate 5a to adjust the protruding length to the wall panel 3 side of the connecting bracket 5, and then one end of the connecting plate 5a is supported by the receiving bracket 4 ) In this way, the inclination of the wall panel 3 and the looseness between the wall panel 3 and the reinforcing material 2 can be eliminated, and the lamination adjustment of the wall panel 3 can be easily performed.

Fig. 8 (a) (b) shows an example of a connecting bracket having a connecting ring 5b formed in a U-shape or annular shape made of reinforcing bars or the like instead of the connecting plate 5a. In this case, the space 5f acts as a cutout 5e for welding the connection hole 5c or the connection hole 5c and the connection nut 5d to pass through the connection bolt formed in the connection plate 5a.

As the reinforcing material 2, for example, it is made of rod-like materials such as reinforcing bars and arch-shaped anchor bodies 6 shown in Figs. 9 (a) to 9 (c), and Figs. 10 (a) to 10 (10). There is an arch-shaped anchor body 6 at the end shown in (e), and may be made of a strip material such as strip steel.

This type of reinforcing material (2) resists drawing on U-shaped bands, but because the bending force does not occur and only the tensile force acts, the material used is less than that of reinforcing steel such as bending grit. It can be planned and is especially excellent for work such as mountain construction.

Also, for example, as shown in Figs. 11A to 11C, reinforcing grit, gold mesh, or dio-textile is used, and in any case, the connection bracket 5 is connected to the end of the wall panel 3 side. The male screw member 15 for screwing the nut 5c protrudes.

When the reinforcing member 2 is formed of a rod-like material such as reinforcing bar, the male screw portion 2a is directly formed at the end of the rod-shaped material as a male screw member as shown in Fig. 4 (a) (b), and is connected to the male screw portion 2a. The connecting nut 5c of the metal fitting 5 is screwed.

When the reinforcing member 2 is formed of a band member such as a band steel, for example, a male thread member is provided at an end of the band member having a rib as shown in FIG. 10 (f) or without a rib as shown in FIG. 10 (g). As the bolt (15), the bolt is protruded, and the coupling nut 5c of the coupling bracket 5 is screwed to the male screw member 15.

When the reinforcing material 2 is formed of a gold mesh or a reinforcing grit, a bar member 16 made of a band steel or the like is attached to an end of the gold mesh or the reinforcing grit as shown in Fig. 11 (a) (b). The male screw member 15 is protruded into

In the case where the diotextile is installed as the reinforcing material 2, the bar member 16 protruding with the male screw member 15 is attached to the end of the diotex tile by winding the end of the diotex tile as shown in FIG. 11 (c). .

In any case, even if the reinforcing material 2 is lowered with the sedimentation of the fill material 1 due to the settlement of the fill material 1 by compression under voltage or the sedimentation of the fill material 1 after construction, the structure of the connection part is extremely simple. Therefore, even when stress concentration occurs, the complex stress does not easily occur, so that the cutting of the reinforcement 2 is not easily performed at the connection portion or the fill portion close to the wall which is easily broken.

In addition, since the end of the wall panel 3 side of the reinforcing member 2 slides downward along the connecting hole 4b of the receiving tool 4 by making the connecting hole 4b a long hole, the wall panel 3 and the reinforcing material ( Since there is no stress in the connection part a with 2), breakage of the connection part a, displacement of the wall panel 3, etc. are reliably prevented.

As a result, the use of the extremely stable thin wall panel 3 having a slide function becomes possible, and construction of a reinforced earth structure excellent in workability and economic feasibility becomes possible.

For example, the anchor bracket 6 is simply formed in a rectangular plate shape (acupressure plate) as shown in FIG. 4, and is pushed in the opposite direction to the wall panel 3 when the fill material 1 is in voltage. For example, when the tension is introduced into the shape, it is formed in a substantially "<" shape as seen from the side shown in FIG. 12 (a), but formed in a rectangular plate shape or a circular plate shape shown in FIG. 12 (b) (c). The reinforcing member 2 shown in Fig. 12 (d) in the reinforcing member made of a rod-like material such as a reinforcing bar or a reinforcing bar with a central portion protruding toward the wall panel 3 side and a reinforcing edge portion on the wall panel 3 side. The end of is bent in a triangular shape and the like, and for example, as shown in Fig. 12 (e) (f) is formed arcuate from a strip of steel or the like.

In particular, in FIG. 12A and FIG. 12B, the protrusions 6a protrude as needed on the surface of the wall panel 3 in order to increase the adhesion of the fill material 1. .

In addition, by making the anchor body 6 of the reinforcing member 2 shown in FIG. 12 (b) (c) in such a shape, even when thin, the rigidity is high, and even when the anchor body 6 is installed, it is strongly pushed into the fill material 1. It does not deform well.

For this reason, since the weight of a member can be reduced and large pullout resistance can be obtained, the effect of economy, carrying property, and workability can also be acquired. On the other hand, when the anchor body 6 having such a shape is pushed into the fill material 1, the shape of the anchor body 6 cannot be accurately installed at a certain place unlike the flat plate.

For this reason, the stiffener 2 between the wall panel 3 and the anchor body 6 is loosened easily, and the wall surface is easily displaced. Therefore, such a defect can be eliminated by using the connection part of the present invention.

8 and 9 particularly show an example of attachment of the anchor body 6 formed in an arc shape, and when rod-shaped materials such as reinforcing bars are used as the reinforcing material 2, as shown in FIGS. 8 (a) to 8 (c). The reinforcing material 2 which adjoins the attachment hole formed in the both ends of the anchor body 6, respectively, is made to pass, and is attached by being firmly inserted into the fixing nut 17 before and behind.

In the case where a band-like material such as a band steel is used as the reinforcing material 2, both ends of the anchor bracket 6 are fixed to the end of the adjacent reinforcing material 2 as shown in FIG. 9 (a) (b), respectively. The bolt is fixed and attached.

In this way, the anchor body 6 attached to the reinforcing material 2 is formed in a semicircular shape, so that the fixing force is extremely large and the wall panel 3 can be fixed more securely.

In such a configuration, the construction method of the reinforcement soil structure according to the present invention will now be described based on FIGS. 13 (a) to 13 (e).

(1) First, the first wall panel (3A) is installed on the foundation (19), which is constructed in advance, and the fill material (1A) is filled on the rear side up to the position of the lower receiving bracket (4). After the voltage, the first reinforcement (A) having the connecting bracket 5 attached thereto is disposed on the fill material 1A.

② Wind the next connecting plate 5a (or connecting ring 5b) properly to adjust the protruding length to the wall panel 3A side of the connecting plate 5a.

(3) Insert one end of the next connecting plate 5a between the flange portions 4a and 4a of the receiving bracket 4, and also connect the connection hole 5c and the receiving bracket 4 of the connecting plate 5a. Tighten the connecting bolt 14 between (4b) to connect the reinforcing material (2A) to the back of the wall panel (3A) through the connecting bracket (5).

At that time, if there is a loosening between the wall panel 3A and the reinforcing material 2A, the connecting bolt 14 is temporarily removed from the connecting hole 4b of the flange 4a, and the connecting plate (from the flange 4a and 4a) is removed. 5a) is removed, and the protruding length of the connecting plate 5a is adjusted by winding the connecting plate 5a again.

④ Then insert the connecting plate (5a) again between the flanges (4a) and (4a) of the receiving bracket (4), and also connect the connecting plate (5a) to the receiving bracket (4) by the connecting bolt (14) again. .

In this case, when the connecting plate 5a is wound in the circumferential direction of the male screw portion 2a, the connecting nut 5d is also wound together, and the protrusion of the connecting plate 5a is moved by moving in the axial direction of the male screw portion (thread cutting portion) 2a. The length is adjusted.

For example, if the screw pitch of the male nut part 2a of the connecting nut 5d and the reinforcing material 2 is 1 mm, the screw pitch can be adjusted by 0.5 mm in half rotation and 1 mm in 1 rotation. The length can be easily adjusted by the number.

If the wall surface can be adjusted in such a unit, the wall displacement hardly occurs, so the wall surface can be assembled.

⑤ Fill the fill material (1B) up to the position of the upper receiving bracket (4) on the next fill material (1A), and carefully apply voltage, and then place the second reinforcement (2B) on the fill material (1B). This completes the installation of the first wall panel 3A and the first reinforcing material 2A supporting the first wall panel 3A.

(6) The second stage wall panel (3B) is installed on the next wall panel (3A) of the first stage, and the filling material (1C) is filled to the position of the lower receiving bracket (4) on the rear side. After the voltage, the reinforcement 3C of the third stage which attached the connection bracket 5 on the fill material 1C is arrange | positioned.

⑦ Wind the next connecting plate (5a) properly and adjust the protruding length to the wall panel (3B) side of the connecting bracket (5). Then, one end of the connecting plate 5a is inserted between the flange portions 4a and 4a of the receiving bracket 4, and the connection hole of the connecting hole 5c and the receiving bracket 4 of the connecting plate 5a. The reinforcing material 2C is connected to the rear part of the wall panel 3B by tightening the connecting bolt 14 between (4b).

At this time, when there is a looseness between the wall panel 3B and the reinforcing material 2C or when the wall panel 3B is inclined, the connecting bolt 14 is pulled out and the connecting plate 5a is separated from the receiving bracket 4. Then, rewind the connecting bracket 5 (connection nut 5d) to adjust the protruding length of the connecting plate 5a and connect the connecting bracket 5 to the receiving bracket 4 again.

For example, suppose that in the above description, the connection bolt 14 was temporarily fixed and the slope of the wall panel 3 was measured to be inclined to 5.5 mm. In addition, the screw pitch of the connection part shall be 1mm.

In the present invention, 0.5mm for each half rotation of the connecting plate 5a (or 5b) in the circumferential direction of the male screw portion 2a, 1mm for every one rotation, and the protruding length of the connecting plate 5a is adjusted. Then, since the connecting plate 5a can be connected to the wall panel 3, the connecting plate 5a is temporarily removed from the receiving bracket 4, and the connecting plate 5a is wound 11 times in the circumferential direction of the male screw portion 2a. ) Back to the wall panel (3) can be accurately upright 5.5mm wall panel (3). In other words, the connection part has a simple structure, so that small adjustments can be precisely performed with a simple operation.

Next, similarly to the third and fourth stage wall panels 3C... And reinforcement (2) is installed alternately with the fill material to build the entire reinforcement soil structure.

Even during such construction, even when the reinforcing material 2 falls with the settlement of the caustic earth material 1 due to the voltage of the fill material 1, the connection part is not easily broken, and in particular, the connection hole 4b is made into a long hole to Since the end portion can slide downward along the connecting hole 4b of the receiving bracket 4, since the stress is not concentrated in the connecting portion a between the wall panel 3 and the reinforcing material 2, the connecting portion a ) Is not broken or the wall panel 3 is inclined.

Fig. 14 (a) (b) shows another example of the reinforcing soil structure according to the present invention, and in particular, the tip of the reinforcing member 2 made of rod-like material such as reinforcing bar has an anchor body 18 having the structure as shown in Fig. 14 (b). It is fixed to Jisan.

In addition, in the case of the structure fixing the anchor body in Jisan, when there is no hill in Jisan, looseness occurs in the reinforcement between some anchor body and the wall panel, and it is easy to deform, but this defect is solved by using the connection part of the present invention. can do.

In the drawing, the tips of the plurality of reinforcing members 2 extending to the hillside side are connected to each other by a fixing bar 19 made of a section steel such as a mountain beam, and the fixing bars 19 are concrete or mortar in the hillock. It is connected to the anchor 21 fixed with 20. The other structure is the same as that demonstrated in FIG.

As described above, in particular, the reinforcement disposed in the wall material and the fill material provided at the front end of the fill material has a connecting plate or a connection ring connected to the receiving bracket protruding from the rear part of the wall material at one end, the reinforcing material at the other end. Since it is connected through connecting brackets having connecting nuts respectively screwed to the protruding male threads, when connecting the reinforcement to the back of the wall material, wrap the connecting nut properly and adjust the protruding length to the wall panel side of the connecting plate. Connecting one end to the receiving bracket eliminates the inclination of the wall panel, the looseness between the wall panel and the reinforcing material, and can simplify the stacking adjustment of the wall panel.

In addition, the connecting bracket is simply formed by attaching a connection hole to one end of the connection plate and a connection nut to the other end. Since there is no process such as screw processing, it can be easily constructed in the field, and the construction cost can be drastically reduced. The effect is that it can be planned.
